​Task.sleep() vs. Task.yield(): The differences explained​

I've used both methods in my code, but sleep has always been easier to understand than Task.yield(). It's time to dive into the differences and showcase a few examples.

QUESTION OF THE WEEK

“
What do you think is a good price for a course?
— Anonymous

As you might know I've recently started working on a new course on Swift Concurrency and Swift 6 (feel free to join the waitlist). One of the questions I started discussing was about a proper price for courses.

If you're looking for a proper pricing for a new product, you can use several research strategies. One of them is the Van Westendorp Pricing Model. You basically ask four questions:

  1. At what price would it be so low that you start to question this product’s quality?
  2. At what price do you think this product is starting to be a bargain?
  3. At what price does this product begin to seem expensive?
  4. At what price is this product too expensive?

You can use the responses to create a line chart and find the optimal pricing for your new product.

I started a similar survey for my new course, and would love your input. It's directly an opportunity for you to experience such pricing model research:
